Study Notes
Linear Functions and Relations
- Linear function: A fundamental concept represented as a straight line, crucial for advanced mathematics.
- Nonlinear: Any function that does not conform to linear characteristics.
- Function: A relationship where one quantity changes in response to another.
Patterns and Types
- Patterns: Can be geometric designs or sequences (algebraic or numeric) with repeating aspects, such as numeric patterns (e.g., 4, 7, 10, 13) involving consistent addition.
- Algebraic pattern: Involves numbers and variables arranged in a specific sequence.
Mathematical Operations and Relationships
- Fact family: A group of numbers connected through various mathematical operations, such as addition and subtraction.
- Algebraic expression: A combination of variables and constants that lacks a relational symbol (e.g., 5y + 8).
- Coefficient: The number that precedes a variable in an expression, indicating the quantity of that variable.
Types of Algebraic Expressions
- Monomial: An algebraic expression consisting of a single term.
- Binomial: An expression with two terms (e.g., 2ab - cd).
- Trinomial: An algebraic expression containing three terms.
- Polynomial: Represents expressions with more than one term.
Graphical Representations
- Graph: Visual representation illustrating numerical relationships.
- Table: An organized listing of values typically arranged in rows and columns to show functions and relationships.
- Pictorial graph: The most tangible representation, transitioning from real objects to symbolic forms.
- Bar Graph: Displays data using horizontal or vertical bars.
- Line Graphs: Illustrates relationships among two or more variables through data points.
- Pie Chart: Visualizes relationships as parts of a whole, typically used for percentages.
Learning Progressions in Mathematics
- Concrete models: Effective tools for younger students (e.g., Kindergarten) to explore patterns through hands-on attributes (e.g., patterns like AB, AAB).
- Transition in learning: By third grade, students progress to using tables and graphs to represent relationships between two variables.
Mathematical Equations and Inequalities
- Equations: Statements asserting the equivalence of two expressions, marked by an equals sign (e.g., (7 + 2 = 10 - 1)).
- Algebraic inequality: Expresses a relationship showing greater or lesser value between variables and constants (e.g., (2x + 8 > 24)).
